Tolong bantu jawab soal limit trigonometri​

Answer 1

Jawab:

limit trigonometri bentuk takj tentu

Penjelasan dengan langkah-langkah:

lim (x-> 1)  [ (x² -1 ) 2 (x -1)  ] / [ - 2 sin² (x - 1) ] =

.

= lim (x-> 1)  [2 (x-1 ) ( x+1) (x -1)  ] / [ - 2 sin² (x - 1) ]

= lim (x-> 1)  [2 (x-1 )² ( x+1)] / [ - 2 sin² (x - 1) ]

=  lim (x-> 1)  [2 (x-1 )²/ -2 sin² ( x -1) ] . lim(x-> 1) (x +1)

=  lim(x-> 1)  - 1 ( x+1)

x= 1

L = - 1 (1+1)

L= - 2
